The world's most difficult railway repair how much force will be open fasteners

It is understood that there are 253 bridges and 159 tunnels across the Yiwan Railway, including 54 double-track tunnels, 34 risk tunnels and 8 first-rate risk tunnels. The total length of the bridge tunnel accounts for 74% of the total length of the line. Tunnel Museum". The project mainly passes through karst landforms, with regional large faults developed, widespread karsts, steep hills, deep river valleys, difficult terrain, and complex geology. It is the most difficult and longest-running mountain railway in the history of railway construction in China. Chinese and foreign experts and peers are recognized as world-class problems.

Challenges and Opportunities for Railway Fasteners The railway fastener industry is one of many industries. Railway fasteners are widely used in the construction of urban rails. In recent years, railroads have been extremely popular and sought after.

Railway rail joints are the source of vibration. In order to overcome the root cause of this vibration and reduce the occurrence of rail joints, the use of railway fasteners is the best choice. Its use eliminates the problems of rail joints and increases joint resistance.

Ensure the safety of railway transportation. Therefore, the construction of railway freight rail transit is inseparable from the “support” of railway fasteners.

According to relevant sources, as of now, about 27 cities are preparing to build urban rail transit, 22 of which have been approved by the State Council. By 2015, 22 cities including Beijing, Shanghai, and Guangzhou will build 79 rail transit lines with a total length of 2259.84 kilometers and a total investment of 88,200.03 million yuan.

According to incomplete statistics, there are about 50 cities in Beijing and Shanghai, and 1154 kilometers of rail transit lines are under construction. With the increasing market capacity of railways and subways, the market demand for railway fasteners is accelerating production.

Although the construction of the railway can not be separated from the role of railway fasteners, not all specifications and models of railway fasteners are suitable for railway construction, the strength of some ordinary railway fasteners can not meet the high-speed rail vibration, railway and subway Rail transit fasteners require high strength rails. With the continuous increase of railway construction, the demand for high-strength railway fasteners in China will also increase rapidly.

Therefore, domestic railway fastener enterprises should gradually reduce the proportion of ordinary railway fasteners and increase the output of high-margin high-strength railway fasteners to meet market demand. According to China's “Eleventh Five-Year Plan” railway development plan and investment plan, from 2008 to 2010 there will be an average annual investment of 350 billion yuan, which will ensure that in the next two years, the compound annual growth rate of railway investment is about 20%.

High-speed rail orders into Jinyi Industrial "Dinghai Pin"

At the end of 2009, Jinyi Industrial received a paper notice from the Ministry of Railways' Transport Bureau. Several fastening systems produced by the company passed the technical review of the Ministry of Railways and could be used on the road.

“This is a historic moment and it is a time that we should remember. Because this is the first time that the Ministry of Railways has applied for the approval of domestic passenger line fastener manufacturers, and through review, we can justify entering China’s high speed. Railway market.” Tu Zhiqing told reporters.

The orders for high-speed rail fasteners will become the new growth point of Jinyi Industry. At present, the large-scale construction of the railway has entered a phase of full-scale deployment. According to calculations, the Ministry of Railways invited the Ministry of Railways to bid for 8,000 to 9,000 kilometers of high-speed railway operations from 2009 to 2010, and the corresponding value of high-speed rail fasteners is almost 8 to 10 billion yuan.

Recalling the close contact between Jinyi Industry and the railway, Tu Zhiqing seems to remember: In April 2002, the Ministry of Railways's Transportation Bureau approved Jinyi Industrial as the “Railway Equipment R&D Base”; in September 2002, the company won the bid for the high torque of the Qinghai-Tibet Railway. Fastening elastic bar type I fasteners screw spikes, locknuts, limit boards; April 2006, preparation of Jinyi high-speed rail fastener production base; August 2006, Zhengxi and Wenfu passenger dedicated line fasteners System; In December 2007, we obtained the “Independent Research and Development Assessment Certificate” for the passenger dedicated line fastening system issued by the Engineering Management Center of the Ministry of Railways; in March 2008, we won the bid for the fastening system of the Yichang-Wanzhou Passenger Dedicated Line in March 2008...

In fact, as early as the beginning of the listing, Jinyi Industrial aimed at the future high-speed railway market in China, and most of the raised funds were used in high-strength special-shaped fasteners.

In 2008, Jinyi Industrial completed 6 technological transformation and technological development projects, with a total investment of 89.091 million yuan. It developed 112 new products, covering six major series of rail transportation, electric power, construction machinery, automobiles, construction steel structures, and household appliances. In particular, continuous improvement of various types of high-speed rail fastening system products.

As the only listed company in the field of high-speed railway fasteners, Jinyi Industrial is the only manufacturer in China that has experience in supplying high-speed fasteners at speeds of 250km/h and 350km/h. In order to ensure safe operations, the Ministry of Railways generally tends to choose suppliers with mature supply experience. The abundant supply experience and strong production capacity make Jinyi Industry enjoy greater market share.

As early as 2006, in the tendering and tendering of the first batch of high-speed rail fastening systems in the country, Jinyi Industry won four packages for the bid, obtained an order of 750 million yuan, and gained a market share of 16%, while the high-speed railway was tendered. The operating mileage is 3,336 kilometers, which is less than half of the operating mileage of the tender. In addition, Jinyi Industrial Co., Ltd. is the only bid winner for the Qinghai-Tibet railway fasteners with the worst climate conditions, and has achieved good cooperation and recognition with various construction units under the Ministry of Railways. It will also benefit from this relationship in the future.

In the current year's bidding, foreign brands accounted for nearly 50% of the market share, while the Ministry of Railways will be more inclined to domestic brands under the policy of localization rate of 70%. In the absence of high-speed rail production capacity of other domestic fastener manufacturers, Jinyi Industrial is likely to increase its market share in the tender for high-speed rail fasteners.

From 2009 to 2010, the Ministry of Railways entered the peak period for high-speed rail fasteners, and Jinyi Industry has already begun to share this feast: On November 18, 2009, Jinyi Industrial won the bid to build a new Beijing-Shijiazhuang Passenger Dedicated Line and Shiwu Railway. The F01 package of 580 million yuan for the passenger dedicated line (Hebei Section) project. In October of the same year, Jinyi Industrial signed a procurement contract of RMB 12.49 million with the China Railway Third Bureau Taizhongyin Railway Luliangshan Tunnel Project; signed a purchase contract of RMB 790 million with the Harbin-Dalian Railway Passenger Dedicated Line; signed a contract with Changji Intercity Railway The purchase contract with a total price of 5.7 million yuan; and the total railway contractor Zhangji Railways signed a procurement contract with a total price of 6.81 million yuan.
